1. A little bleach in water when you brush /wash the feeder should do the job. Make sure you rinse it off well. Truth be told, the bees manage to coexist with the mold, so don't worry if some remains. They do a good job of cleaning it themselves.
2. Sounds like your diagnosis is right on target--feed fumagillin.
3. Try to condence the sealed food frames toward center, let them clean out the uncapped honey from the sides. Don't leave empty supers on the hive, it just means they have to heat up a larger space.

 

Hey Joe:

Can't help with the beemax thing because I am not sure if scrubbing with a bleachy solution might damage it.

If the brown spots are dysentry and it's bad, Fumagilan-B (if you are treating) is the right product. You might also want to make sure you have adequate ventilation.

Are you running double deep brood chambers? If so, is the top one full of stores (or almost)? I would remove the super that has 25% comb and no honey, no point in leaving that on there at all. Leave the one with 80% comb and honey.
If you do not have additional stores of honey in that top deep, I think only having 1 super for NY is not near enough.

 

Ha ha, Efmesch beat me to it! :thumbsup: :lol:

 

Perry, Looks like we think pretty much alike, :thumbsup:

 

If you don't have any top entrances or top ventilation holes, you should probably add some to help ventilation. Dysentary thrives in a closed up hive, and winter condensation can be a death knell.

 

what Omie said + nosema is known to like cool and damp conditions. ventilation as she suggest can be critical as can be the location where you have the hive placed. in any possible damp location even the direction of the entrances can be critical in regards to minimizing nosema.

I think perhaps I drove thru your little town this summer. I wanted to stop the night and take a good look around but there was no place in the Inn.... actually if the place is where I think it is the rooms were a bit too pricey so we must kept truckin' on down the line.
